Security Testing
Identify and fix vulnerabilities with penetration tests, input validations, and secure coding audits.
Secure Your AppOverview
Your application’s security is critical. GullySystem provides manual and automated security testing to uncover vulnerabilities, protect sensitive data, and ensure compliance with global standards. From code reviews to simulated attacks—we secure every layer of your stack.
Benefits
Prevent Data Breaches
Find and fix flaws that could expose user data, financial details, or system access before attackers do.
Compliance Readiness
Meet regulatory standards like GDPR, HIPAA, or PCI DSS by validating your app's security posture.
Risk Mitigation
Detect and patch threats from outdated plugins, misconfigurations, or bad auth logic before they’re exploited.
Safe Deployments
Run pre-launch security tests to ensure every release is hardened against real-world attack vectors.
Reputation Protection
Avoid costly incidents and user trust issues by proactively identifying and resolving vulnerabilities.
End-to-End Security Review
From login to API to database—we review your full stack for insecure flows, tokens, or permissions.
Our Testing Approach
Vulnerability Scanning
Use tools like OWASP ZAP, Nessus, and Nikto to identify known vulnerabilities and misconfigurations.
Penetration Testing
Simulate real-world attacks to expose weaknesses in authentication, session handling, and inputs.
Code & Dependency Audit
Review source code, libraries, and third-party dependencies for insecure logic and CVE vulnerabilities.
API Security Testing
Test REST and GraphQL endpoints for issues like injection, broken auth, data exposure, and rate limits.
Form & Input Validation Checks
Ensure all forms and fields sanitise inputs to block XSS, SQL injection, and command execution risks.
Access Control Testing
Verify roles, permissions, and session management across users, admins, and guests for privilege escalation flaws.
Tools & Technologies We Use
OWASP ZAP
Automated scanning for injection flaws, broken access control, and insecure headers in web apps.
Burp Suite
Manual and automated penetration testing tool for testing inputs, tokens, and API interactions.
Nessus / Nikto
Scan servers and applications for outdated components, open ports, and security misconfigurations.
SonarQube
Static code analysis to catch bad patterns, hardcoded secrets, and unvalidated inputs early in dev.
Postman Security Collections
API security checks using custom scripts to test headers, tokens, rate limits, and response integrity.
Snyk / npm audit
Check package vulnerabilities and update insecure dependencies in Node, PHP, Python, and Java stacks.
